A support for household appliance includes a hydraulic plate which is fixed to the bottom of the household appliance; a sheath, which is fixedly connected with the hydraulic plate; a regulating support, which is arranged in the sheath and is axially movable relative to the sheath; an accommodation chamber, which is formed by the hydraulic plate, the sheath and the regulating support; and a flexible accommodation body, which accommodates a liquid medium and is arranged in the accommodation chamber. The flexible accommodation body extends and retracts to drive the regulating support to axially move in the sheath for leveling under the action of pressure. The hydraulic plate and the sheath can be rapidly, reliably and fixedly connected, the requirements on the strength of connection between the hydraulic plate and the sheath are lowered, and the essential space and height required by the connection are further lowered.

An object of the present disclosure is to provide a high strength aluminum alloy material having a ribbon shape, which can be an alternative to copper-based materials and iron-based materials having a ribbon shape, and a conductive member, a conductive component, a spring member, a spring component, a semiconductor module member, a semiconductor module component, a structural member and a structural component including the aluminum alloy material. The aluminum alloy material of the present disclosure has an alloy composition containing Mg: 0.2% to 1.8% by mass, Si: 0.2% to 2.0% by mass, and Fe: 0.01% to 1.50% by mass, with the balance being Al and inevitable impurities, wherein the aluminum alloy material has a Vickers hardness (HV) of 90 or more and 190 or less and has a ribbon shape.

The present disclosure discloses an electromagnetic multistage adjustable variable inertance and variable damping device. Iron cores are magnetized by winding electromagnetic coil windings outside the iron cores and applying an electric current action to the electromagnetic coil windings, and air gap magnetic fields are generated by the magnetized iron cores and permanent magnets in air gaps to cause the variation of shear damping forces between a driving shear plate and magnet yokes and between driven shear plates and magnet yokes, which avoids that the mechanical properties of an inerter cannot be fully utilized due to the friction caused by mutual contact among parts, thereby realizing multistage real-time adjustability of an instance coefficient and a damping coefficient of the device.

A crossbar assembly for facilitating isolation of a sensor assembly from vibration of a payload mounting system on a vehicle comprising an outer crossbar segment, an inner crossbar segment, an isolator, and a damper. The outer crossbar segment comprises a payload mount interface operable to mount to a payload mount, and an outer isolator interface operable to mount to an isolator. The inner crossbar segment comprises a structure interface to mount to a structure, and an inner isolator interface operable to mount to the isolator. The isolator can be supported by the outer and inner crossbar segments. The damper is adjacent the isolator. The isolator is operable to deform in response to relative movement between the outer and inner crossbar segments. The isolator operates to partially decouple the outer crossbar segment from the inner crossbar segment and the damper dampens vibrations propagating between the outer and inner crossbar segments.

A bearing bush for supporting a motor vehicle part includes an inner tube made of a metal, a sliding sleeve made of a first plastic material and mounted rotatably on the inner tube, and an elastomer bearing which surrounds the sliding sleeve and has at least a first elastomer body and an outer sleeve. A sliding layer made of a second plastic material is applied to an outer circumferential surface of the inner tube, the first plastic material and the second plastic material forming a tribological pairing either of two different polymers from the groups of polyamides, polyoxymethylenes, polyketones, fluoropolymers, polyethylene terephthalates or polybutylene terephthalates, or the tribological pairing being formed from polyketone against polyketone, wherein the polymers of the tribological pairings each are present in a continuous thermoplastic polymer phase.

A method of manufacturing a hollow coil spring which is made of a hollow wire in which a terminal sealed portion is formed on an end portion of the wire. The terminal sealed portion has a rotationally symmetric shape in which an axis passing through the center of the wire is the symmetric axis. The hollow coil spring includes an end wall portion, and an end face arc-shaped curved surface. The end wall portion includes an end face perpendicular to the axis. A distal-end-center closure portion is formed on the axis at the center of the end wall portion. A spring seat includes a base member and a sheet member. An end turn portion of the hollow coil spring is in contact with the sheet member. The end face of the end turn portion is opposed to a stopper wall of the spring seat.

A damper unit for use in a vibration-reducing assembly for a steering wheel is disclosed. The damper unit includes a slider configured, upon horn activation, to slide on a guide shaft. A damper element made from an elastomeric material is arranged on a first part of the slider. A molded horn spring element is molded directly on a second part of the slider and is configured to exert a spring force on the slider. The damper unit provides a unitary structure providing both a vibration damping function and a horn spring function in one single assembly unit, reducing the number of components to assemble. A vibration-reducing damper assembly including one or more such damper units is also disclosed, as well as a method of making such a damper unit.

A frictional damper is designed with a tubular housing having a longitudinal axis, with a tappet, which is displaceable in the housing along the longitudinal axis and is led out at an open end of the housing, with a frictional element lying against the tappet and with a cap attached to the open end of the housing with axial prestressing relative to the longitudinal axis.

A body mount comprises a first support member adapted to engage a body of a vehicle and a second support member adapted to engage a frame of the vehicle. The second support member includes a tubular portion disposed radially inward of a second support surface. A first elastomeric spring interconnects an inner tube and the second support member. The first elastomeric spring is positioned within the tubular portion. A hydraulic damping system is disposed on a side of the second support surface opposite the first support member and includes a housing coupled to the second support member. Second, third and fourth elastomeric springs are positioned within the housing. The second elastomeric spring and the third elastomeric spring are spaced apart by a first track. The third elastomeric spring and the fourth elastomeric spring are spaced apart by a second track.
